A celestial object called a pulsar emits its light in short bursts that are synchronized with its rotation. A pulsar in the Crab Nebula is rotating at a rate of 30 revolutions/second. What is the maximum radius of the pulsar, if no part of its surface can move faster than the speed of light (3  108 m/s)?

Question 2

What is the angular momentum of the moon about the Earth? The mass of the moon is 7.35  1022 kg, the center-to-center separation of the Earth and the moon is 3.84  105 km, and the orbital period of the moon is 27.3 days. Ignore the small offset of the center of mass of the system from the center of the Earth in your calculation.
